A virtual reality gaming system known as the "Nerve Gear" is finally released to the public alongside the world's first virtual reality game called "Sword Art Online" (SAO).

After a few hours, Kirito and Klein discover that they cannot log-out. Akihiko Kayaba, the game's creator and employee of the computer corporation Argus, announces to the players that he intentionally removed the log-out option and that all players will die if their Nerve Gear is forcefully removed or their in-game health bar is depleted to zero. He informs them that he created this game as a way to become God over his own dominion. The only way to escape is to clear all 100 floors of Aincrad.

Parties are formed, and Kirito teams up with a young girl named Asuna. The next day, Diabel's raid group arrives at the boss' room and battles Illfang and his minions. When Illfang's health becomes low, Diabel goes for the finishing attack. Kirito attempts to warn him, but Illfang attacks down first and mortally wounds Diabel.

On June 12, 2023, while Keita goes to buy a house for the guild, the other Black Cats members decide to earn some money by going to the upper floor dungeons. However, they become trapped in a room with higher-level monsters. Unable to save them, Kirito watches as the Black Cats are killed, including Sachi.

He tells her of an item at the Hill of Memories on the 47th floor, which can revive her familiar within three days of its death, and offers to accompany her there. As they spend time together, Kirito warns Silica of "orange players", players who commit crimes, and "red players", players who kill other players. When they finally retrieve the item, the Pneuma Flower, they are confronted by Rosalia and her men, who are members of Titan's Hand, an orange-player guild, and are after the flower. Kirito then reveals that his true motivation for escorting Silica was to draw Rosalia out and arrest her. The guild realizes Kirito is the infamous Beater, "The Black Swordsman".

However, Kirito opposes the plan, as the non-player character villagers will be killed. A month later, on the 59th floor, Asuna finds Kirito taking a nap, and chastises him for being lazy. Kirito persuades her to relax, and she falls asleep. To repay him for guarding her while she was asleep, Asuna offers to buy dinner for him, but their meal is interrupted by a scream. They rush out of the restaurant to find a player, Kains, hanging outside a church, impaled with a spear. He dies immediately after.

Kirito and Asuna continue to investigate the murder of Kains and Yolko, who were members of a disbanded guild called Golden Apple. Kirito wonders how it is possible to kill someone in a safe zone. Schmit, another former member of Golden Apple, declares that the killer is the ghost of Griselda, their deceased leader. After watching a dropped sandwich vanish, Kirito deduces how Yolko and Kains "died", and later, who murdered Griselda. He explains to Asuna that Yolko and Kains have faked their deaths by using a teleport crystal when their armor broke from losing durability, which made them appear to have died. Yolko and Kains confront Schmit at Griselda's grave to investigate the identity of Griselda's killer. After Schmit explains that he had only followed instructions given to him and had not expected Griselda's death, the three are surrounded by members of a notorious player killers guild, Laughing Coffin, who have come to kill them.

Angry and with her pride hurt, Lisbeth persuades Kirito to let her accompany him to the Western Mountain on the 55th floor to get a rare mineral from a dragon that eats crystals, so that she can use the mineral to make a stronger sword. When they arrive at the Western Mountain, Kirito tells her to hide when he fights the dragon. However, she ignores his advice and emerges from hiding halfway through the battle. The dragon blasts Lisbeth into a deep pit with Kirito jumping in to save her. The next morning, Kirito discovers that the mineral they are seeking, a Crystallite Ingot, is under the snow as the hole is the dragon's nest. The dragon returns and Kirito grabs Liz with him as he stabs the dragon's back, forcing it to carry them out. Now safe and with the mineral in hand, Liz creates a new sword, Dark Repulsor, for Kirito and denies the payment.

As the soldiers rest, their leader Corbatz demands Kirito give them the map he made of the floor. Despite Asuna and Klein's protests, Kirito complies with his request.

Just as Kirito is about to deal the winning strike, Heathcliff mysteriously manages to parry it and defeats Kirito. Now a member of the Knights of the Blood Oath, Kirito is questioned by Asuna about the reason for his strong aversion to joining guilds. After he confides in her about what happened to the Midnight Black Cats, Asuna comforts Kirito and says she will protect him. Later, Kirito is asked by a fellow member, Godfree, to follow him and a seemingly remorseful Kuradeel to the 55th floor dungeons for a skill assessment.

They go on a vacation and stay at their new home in a village on the 22nd floor. The couple later find a lost girl in the forest and see her suddenly collapse. As they approach the unconscious girl, they discover that she does not have a cursor above her, suggesting a glitch meaning a software error. They take the girl to their home and she wakes up the following day. However, upon questioning from Asuna and Kirito, the girl is able to remember her name, Yui. Yui calls Asuna and Kirito "Mama" and "Papa", respectively, which Asuna and Kirito happily agree to. They decide to go to the Town of Beginnings to see if they can find anybody that knows Yui. Instead, they find a young woman named Sasha and the children she's taking care of being extorted by the Holy Dragon Army for taxes.

They arrive at Thinker's location in the dungeon, and are attacked by a boss called the "Fatal Scythe". As the boss is about to strike down Kirito, Yui jumps in between them. The boss attacks, but is unable to damage her because she is an "Immortal Object", which means the system will not allow her to take any critical damage. Yui recovers her memories, and reveals herself as artificial intelligence, a simulation of human-like intelligence and behaviors. Despite the revelation, Asuna and Kirito still accept Yui as their "daughter", but Yui bids them farewell when she realizes that she is going to be deleted for her interference in the game.

Kirito deduces that Heathcliff is, in fact, Akihiko Kayaba himself, by exposing him as an "Immortal Object". Akihiko paralyzes everyone except Kirito, and reveals that he would have been the final floor's boss. He offers Kirito the chance to face him in a one-on-one duel. If Kirito wins, Akihiko will consider the game beaten and log out all the remaining players. After giving his best wishes to the others, Kirito accepts the challenge. Asuna sacrifices herself to save Kirito, despite the fact that she is paralyzed and so should be unable to move. After Asuna dies, Kirito is stricken by grief, and attacks Heathcliff with little will. Heathcliff easily kills Kirito, but Kirito overrides the Death system, recovering at zero health and killing Heathcliff. By doing this, the game is declared cleared.

He then bids farewell to the couple, and congratulates them on clearing the game. Kirito and Asuna tell one another their real names, Kazuto Kirigaya and Asuna Yukki, and embrace as the world falls apart. To his surprise, Kazuto awakens in a hospital in the real world.

Just as things begin to look dire, Sakuya and Alicia arrive with their armies to back them up.

Arriving at the top of the World Tree, Kirito and Yui finally reunite with Asuna. However, they are suddenly hit by high gravity magic, which forces Yui to retreat, and they are confronted by Oberon. As Oberon reveals that his plans to control the human mind are almost complete, he chains Asuna and attempts to molest her in front of Kirito. Falling into despair, Kirito hears the voice of Akihiko, who encourages him to stand up and fight. Using Akihiko's administrative functions, Kirito removes Oberon's powers and challenges him to a fight with no pain absorption, and shows Oberon what true pain is before destroying him. After logging Asuna out to ensure her safety in the real world, Kirito meets with a remnant of Akihiko's memory, who gives him an item called "The Seed" before leaving.

Rushing to the hospital, Kazuto is attacked by an injured Sugou wielding a knife. Kazuto disarms him and, considering Sugou's actions, ultimately spares his life. Kazuto finally meets with Asuna, and they have a tearful reunion. On May 16, 2025, Kazuto and Asuna attend a special school for students who were trapped in SAO. As they have lunch, Kazuto reveals that Sugou was captured by the police after their fight and that his crimes have been exposed by one of his employees. The 300 players that were trapped by Sugou have been released, but his experiments shocked the public. Later, Asuna, Kazuto, and Suguha head to Andrew's bar, along with Liz/Rika Shinozaki, Silica/Keiko Ayano, Yolko, Kains, Sasha, Yulier, Thinker, Klein/Ryōtarō Tsuboi, and his guild, where they finally have a proper celebration for clearing SAO and ALO. Kirito uploads the World Seed to the Internet, which revives the virtual reality gaming genre.

Kazuto and Suguha meet Asuna, Rika, and Keiko at their high school, where the trio have agreed to teach Suguha how to swim, in preparation for a quest in ALO so that Yui can see a whale for the first time. Meanwhile, Kazuto makes his way to the counseling office, where he meets Kikuoka Seijiro—a member of the Ministry of Internal Affairs. While investigating the SAO incident, Kazuto relates his experiences and previous actions in the game to Kikouka, so he can grasp Akihiko Kayaba's motives while also forcing Kazuto to reflect on his actions throughout the death game. After Kirito defeats Kayaba and gains no insight into his goal, Kazuto's story enters the ALFheim stage, rescuing Asuna and freeing all captive players with the help of his new-found friends. As Suguha eventually learns how to swim, Kazuto concludes his story by explaining the cost of power and leaves Kikouka. Later, Kirito, Asuna, Leafa, Silica, Lizbeth with Klein and Agil went to Turtle Island. They dive into the ocean and arrive at an undersea temple where they met Nerakk, a non-player character. The group begins the quest where they will retrieve a stolen pearl from the temple and return it to Nerakk. The group then found the pearl after exploring, but Asuna notices that it is an egg all along. Nerakk starts to reveal his true form that he is originally Krakken—The Abyss Lord, a very powerful monster which attacks and gives them severe damage. Just when all begins to be lost, Leviathan, the Sea King stops the Krakken and after a brief talk, the Krakken retreats. Leviathan then retrieves the egg, clearing the quest and returns the group to the surface on the back of a giant whale—their reward.
